Client for OGC Sensor Observation Services

A client for Sensor Observation Services (SOS, see <>) as specified by the Open Geospatial Consortium (OGC). With the package users can retrieve (meta)data from SOS instances and interactively create requests for near real-time observation data based on the available sensors, phenomena, observations etc. using thematic, temporal, and spatial filtering.

o EXTENDED documentation: added reference to cheat sheet in Vignette

Changes in sos4R Version 0.2-9 - 2012-08-08

o UPDATED cheat sheet and vignette: added link to Bugzilla

o ADDED minor improvements for sensor description parsing and coecion: sosCoordinates(SensorML) tries to handle 'easting'/'northing', 'longitude'/'latitude', and 'elevation'/'altitude' coordinates and subsequently plotting does not break if 'x'/'y' are not given.

o ADDED function to reset the parsers to default: sos <- SosResetParsingFunctions(sos)

Changes in sos4R Version 0.2-7 - 2011-12-02

o ADDED describeSensor can now handle a character vector of procedures, will return a list with the sensor descriptions
